As shown in 9-39797, FIG.
The structure was as shown in Fig. 7.

An example of the above-described conventional vending machine with an induction heating device will be described below with reference to the drawings.

In the figure, reference numeral 1 is a main body of a vending machine, in which a cooling storage chamber 3 surrounded by a heat insulating chamber 2 is formed. Reference numeral 4 denotes a door provided on the front surface of the main body 1, on the front surface of which selection switches 5 and 5, an article take-out port 6 and the like are provided, and on the back surface of which a heat insulating wall 7 is provided. The heat insulation wall 7 closes the front opening of the cooling storage chamber 3, however, a sales article discharge port 8 that connects the cooling storage chamber 3 and the article extraction port 6 is formed below. The discharge port 8 is always closed by an opening / closing lid 9. Therefore, the cooling storage chamber 3 is provided with a cooling device and a delivery mechanism (not shown) for delivering one article in response to a sales instruction. Reference numeral 10 is an inclined guide path for guiding the articles for sale sent from the sending mechanism to the outlet 8. Reference numeral 11 is an induction heating cylinder provided between the tip end portion 10 ′ of the inclined guide path 10 and the discharge port 8. Reference numeral 12 is a high frequency induction coil integrally molded with the induction heating cylinder 11. Therefore, the upper end of the induction heating cylinder 11 has an inclined opening surface 13, and the inclined guide path 10 is formed.
It is inclined at an angle along the inclination of. Further, the inclined opening surface 13 is configured so as not to project above an extension line of the inclined guide path 10, that is, a line connecting the tip portion 10 ′ of the inclined guide path 10 and the lower edge of the discharge port 8. A push-up device 14 is composed of a push-up plate 15 which is normally located at the bottom of the induction heating cylinder 11, an actuating rod 16 for vertically moving the push-up plate 15, and a drive device 17 for driving the actuating rod 16. There is. Then, the upper surface of the push-up plate portion 15 is
It is formed in an inclined shape along the inclination of the inclined opening surface 13. The push-up plate portion 15 is pushed up by the actuating rod 16 through the inside of the induction heating cylinder 11 to the inclined opening surface 13 (the position indicated by the dashed line in FIG. 7).

Reference numeral 18 denotes a guide / locking device for the actuating rod 16, which can lock the actuating rod 16 at a position where the push-up plate portion 15 reaches the inclined opening surface 13.

Next, the operation of the above conventional configuration will be described.

First, the can a sent out by the sales command rolls along the inclined guide path 10 as shown by the arrow in FIG.
3 falls into the induction heating cylinder 11. The dropped can a ′ is received by the push-up plate portion 15 and heated in that state.
When the heating is completed, the push-up device 14 operates and the can a'is pushed up to the inclined opening surface 13 again. When pushed up to the inclined opening surface 13, the push-up plate portion 15 is inclined, so that the can a '
Is naturally rolled and discharged from the outlet 8 to the outlet 6.

Problems to be Solved by the Invention However, in the above-described configuration, the wall surface of the induction heating cylinder 11 is configured to be substantially vertical so that the cans a and a'can be introduced and discharged. There is a problem that the heating efficiency is low because the end portion is not in close contact with the heated can a'and is apart.

Further, in order to facilitate the introduction and discharge of the cans a and a ', the inner size of the induction heating cylinder 11 is made longer than the size of the cans a and a'in the longitudinal direction to allow a margin. There is a problem in that one end of the can a'gets into the inside of the container to cause burning of the can.

To describe this can burning in detail, the induced currents generated on the wall surface of the can a ′ by the high frequency induction coil 12 are disconnected from each other at the joint portion when the wall surface is composed of the cylindrical portion, the lid and the bottom. Therefore, they occur independently in a closed loop on the wall surface of each can.

Here, if the length of the can a'is shorter than that of the high frequency induction coil 12, or if the can a'is not placed at an appropriate heating position, one end of the can a'will enter the inside of the high frequency induction coil 12. At this time, the induced current in the longitudinal direction of the can a ′ is parallel to the longitudinal coil elements of the can a ′ among the plurality of coil elements forming the high frequency induction coil 12, and is substantially equal to the distance between the coil elements. Flow at intervals.

However, since the wall surfaces of the can a'are disconnected from each other, the induced current in the circumferential direction of the cylindrical wall flows concentratedly near the joint between the lid and the bottom of the can a'and the cylindrical wall. become.
Therefore, as the length of the can a ′ becomes shorter than that of the high frequency induction coil 12, the current density of the induced current in the circumferential direction flowing in the vicinity of the joint increases, and the vicinity of the joint has an abnormally high temperature and can burns.

Moreover, in the high frequency induction coil 12, when the coil element of the portion which is substantially parallel to the cylindrical wall surface of the can a'and does not face the cylindrical wall surface is, for example, on the lid side of the can a ',
The magnetic flux generated by this coil element is concentrated near the joint with the cylindrical wall surface on the lid side wall surface of the can a ′, and the induced current generated by this magnetic flux further raises the temperature near the joint. Further, when the coil element of the portion substantially parallel to the cylindrical wall surface of the can a'and not facing the cylindrical wall surface is on the bottom side of the can a ', the joint portion between the bottom side wall surface and the cylindrical wall surface is formed. The surrounding area gets even hotter.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an automatic vending machine with an induction heating device that can efficiently heat canned beverages and does not cause canning.
